652.

UNREVIEWED SAFETY QUESTION PROCESS. The mechanism for keeping a safety

basis current by reviewing potential unreviewed safety questions, reporting unreviewed safety

unreviewed safety question. [10 CFR 830.3]

653.

UPGRADE. A design and construction measure taken to increase the resistance of structures,

systems, and components for the effects of natural phenomena hazards. Upgrade,

accomplishes the task for which it was written. [EH62dd1]

656.

VALUE ENGINEERING (VE). An organized effort directed at analyzing the functions of

systems, equipment, facilities, services, and supplies for the purpose of achieving the essential

functions at the lowest life-cycle cost consistent with required performance, reliability, quality,

and safety. For the purpose of DOE O 430.1B, value analysis, value management, and value

control are considered synonymous with VE. [DOE O 430.1B]

657.

VERIFICATION (DESIGN). Process of checking that the retrieved design information is

complete and has been accurately translated from the source documents. [EH62dd1]
